304 Stainless Steel DIN 988 Precision Shim Washers
Our 304 Stainless Steel DIN 988 Shim Washers (also known as adjusting or support washers) are ultra-precision flat spacers designed to adjust axial clearances and eliminate play in mechanical assemblies.
Manufactured strictly in accordance with DIN 988 standards using premium-grade SS304, these thin shims offer exceptional thickness tolerance and excellent corrosion resistance. They are widely used to pre-load bearings, align gears, and compensate for tolerance build-ups in automotive, aerospace, pump, and heavy machinery industries.
Key Features & Advantages
High-Precision Thickness Tolerance
When eliminating axial play, micrometers matter. Our DIN 988 shims undergo rigorous precision rolling and stamping processes to guarantee ultra-tight thickness tolerances, ensuring stable performance in high-RPM rotating shafts.
Premium 304 Stainless Steel (Anti-Magnetic & Anti-Corrosive)
Unlike standard carbon steel shims that rust and freeze assemblies over time, our SS304 shims offer superior resistance to chemicals, moisture, and oxidation. Perfect for food processing, marine, and outdoor operations.
Flawless Flatness & Burr-Free Edges
Utilizing advanced fine-blanking technology and multi-stage tumbling, every shim washer features excellent flatness and perfectly rounded, burr-free edges. This prevents localized stress concentration and reduces mechanical wear on mating surfaces.
Comprehensive Thickness Stacking Options
We offer mixed-thickness assortment kits or single-size bulk packages, allowing engineers to stack multiple thin shims (e.g., 0.1mm + 0.2mm) to achieve the exact clearance compensation required.
Typical Industrial Applications
DIN 988 precision washers are vital components anywhere components rotate or require exact spacing alignment:
- Bearing Preloading: Adjusting the distance between bearings to reduce noise and friction.
- Gearbox & Transmission Systems: Setting precise backlash and gear meshing.
- Pumps & Valves: Aligning impellers and sealing rings to prevent fluid leakage.
- Electric Motors: Controlling the axial movement of the motor rotor shaft.
